Foam Insulated Core
We build countless bottle cap prototypes and tested each design in both hot and cold water. We found thermo depreciate quickly at the bottle neck area, with our introduction of FIC, our bottles gain extra 2 hours thermo protection with hot water and 5 hours with cold water.
Steel shield bottom
We’ve implemented our food-grade stainless steel protection shield at the bottom of every bq bottle cap. It protects your drink inside a 360 stainless steel environment.
Silicon soft grip
We want zero detent and smooth to touch design bottle cap. However, we also want to make sure people can grip tight while opening our bottle. The solution is adding a matching color silicon soft grip at the peak of the curve.
Double silicone gasket
Short answer: Double the seal. Long answer: we kept one gasket closest to the Steel Shield and another gasket at the lips of the bottle. We gain longer gasket life cycle and better thermo seal.
